Terraforming, wall detail and maybe some more trees added in. For the entrance, you only used fences for the top half, so try adding in some detail there. Make the roofs pop out at people, don't just use one block and and a 1/2 block incline for the roof. It looks like the style you were trying for was a bit of medieval, so if you look at the roofs, they are steep, the roofs you made aren't as nearly as steep as they should be. It was a good attempt, but you just need more detail and change some of the structure (Roofs of the house-things).
